This chapter synthesizes the arguments of Solar Power Capitalism by theorizing how insertion and depletion constitute the twin engines of the global green energy economy. It argues that solar power capitalism thrives on the incorporation of marginalized people and ecologies into circuits of accumulation while exhausting their labor, health, and time to stabilize those circuits. Through this dialectical framework, the chapter connects extraction, enclosure, household finance, and toxic afterlives of e-waste as interlinked sites of depletion. It situates Africa’s solar energy frontier within global capitalism, showing how decarbonization reproduces inequalities through financialization and patriarchal governance. But the chapter also identifies practices of solidarity that signal alternative futures grounded in care rather than capital. It concludes that confronting depletion is essential to imagining an energy transition organized around collective survival.
